Seeing sound waves

"Seeing Sound Waves" is the title of this YouTube video

I can only speculate about what we're seeing here.  It's an art project using sound waves.  Is that salt on a board that's vibrating above a speaker?  Any ideas out there?

Whatever it is, it's a nice example of naturally occurring symmetry.
